Description

Technical Field

[0001] The invention relates to the field of valves, and in particular to a one-way valve with adjustable one-way direction. Background Art

[0002] A one-way valve, also known as a check valve or non-return valve, has the following functions: the fluid flows in from a specific water inlet end and flows out from a specific water outlet end, while the fluid cannot flow in the opposite direction. This characteristic of the one-way valve makes it widely used in the field of fluid control. It is often used in pipeline systems to prevent the medium (liquid, gas) flowing in the pipeline from flowing back or reflowing. The most common one-way valve on the market is a spring-type one-way valve, which relies on the pressure of the liquid to push open the valve core controlled by the spring. After the pressure disappears, the spring force presses the valve core against the inlet again to block the backflow of the liquid. When it is necessary to adjust the opening pressure of the liquid outlet, it can be achieved by adjusting the stiffness or compression of the spring, while the existing one-way valves can only conduct in one direction, and cannot be switched in one direction by control. This makes the application scenarios of the one-way valves in the prior art relatively single, unable to meet more usage requirements and increase the assembly and use costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects that the one-way valve in the prior art can only conduct in one direction but cannot switch the one-way direction through control. The applicable scenarios are relatively single, and it cannot meet more usage requirements and increase the assembly and use costs. A one-way valve with adjustable one-way direction is provided.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A one-way valve with adjustable one-way direction, characterized in that it comprises:

[0006] A valve body, the valve body comprising a valve cavity for fluid to pass through, the valve cavity comprising a first end and a second end opposite to each other and a first opening and a second opening respectively arranged at the first end and the second end;

[0007] A moving valve core, the moving valve core is located in the valve cavity, and the moving valve core can be moved to the first port position to close the first port or moved to the second port position to close the second port;

[0008] A driving component is provided, wherein the driving component is capable of applying a force toward the first end or the second end to the moving valve core and driving the moving valve core to move and keep closing the first port or the second port.

[0009] In this solution, the above structure is adopted, and the driving component can give the moving valve core forces in two different directions so that the moving valve core switches between two states. In the first state, the driving component applies a force toward the first end to the moving valve core, and the moving valve core moves toward the first end to the first port position under the action of the driving component and closes the first port. In this state, only when the water pressure direction is from the first end to the second end, the moving valve core will be pushed open and the water will flow from the first end to the second end and pass through the valve cavity. When the water pressure direction is from the second end to the first end, the moving valve core will be pressed tightly against the first port, so that it cannot be conducted. In the second state, the driving component applies a force toward the second end to the moving valve core, and the moving valve core moves toward the second end to the second port position under the action of the driving component and closes the second port. In this state, only when the water pressure direction is from the second end to the first end and the pressure applied by the water pressure on the moving valve core is greater than the driving force applied by the driving component, will the driving component be pushed open so that the water flows from the second end to the first end and passes through the valve cavity. When the water pressure direction is from the first end to the second end, the moving valve core will be pressed against the second port and thus cannot be conducted. This solution can realize the timely switching of the conducting direction of the one-way valve, can make the one-way valve more applicable to various scenarios, meet more usage requirements and reduce assembly and use costs.

[0010] Preferably, the drive assembly includes a drive part and a transmission part, the transmission part is arranged in the valve cavity and connected to the moving valve core, and the drive part can drive the transmission part to move toward the first end or the second end and drive the moving valve core to move.

[0011] In this solution, the above structure is adopted, and the transmission part is arranged in the valve cavity, which can improve the sealing performance of the one-way valve and avoid the transmission component being arranged outside the valve cavity, resulting in additional gaps and openings that reduce the sealing performance.

[0012] Preferably, the driving part is arranged outside the valve body, and the driving part drives the transmission part to move by magnetic force.

[0013] In this solution, the above structure is adopted, the driving part is arranged on the outside and drives the transmission part located in the valve cavity by magnetic force, without any physical connection. It is not necessary to open an additional opening on the valve body or set an additional connection transmission structure to control the moving valve core inside the valve body from the outside of the valve body, thereby improving the surface integrity of the valve body and thus improving the sealing degree of the valve, and reducing the structural complexity to make the valve body structure simple.

[0014] Preferably, the driving part includes a first magnetic member, and the transmission part includes a second magnetic member, the first magnetic member can move back and forth between the first end and the second end on the valve body, and the second magnetic member can move synchronously in response to the first magnetic member.

[0015] In the present solution, the above-mentioned structure is adopted, and the driving part and the transmission part respectively include a first magnetic part and a second magnetic part that can interact with each other. The movement of the first magnetic part outside the valve body drives the second magnetic part to move synchronously in the valve cavity to realize the movement of the moving valve core toward the first end or the second end. The structure is simple and the solution cost is low.

[0016] Preferably, the transmission part comprises an elastic member, one end of the elastic member is connected to the second magnetic member, and the other end of the elastic member is connected to the moving valve core.

[0017] In this solution, the above-mentioned structure is adopted, and the transmission part is connected to the moving valve core through an elastic part, which can provide a certain holding force and restoring ability to the moving valve core while transmitting kinetic energy, so that the water pressure needs to reach a certain level to overcome the force of the elastic part to open the moving valve core, and the moving valve core can be reset after the water pressure is reduced.

[0018] Preferably, the driving part includes a fixing part, the fixing part is connected to the first magnetic part, the fixing part includes a limiting groove, an elastic limiting part is arranged on the valve body, and the driving part is movable, and the elastic limiting part can be clamped in the limiting groove to fix the driving part at the first end or the second end position.

[0019] In this solution, the above structure is adopted, and through the cooperation of the elastic limiting member and the limiting groove, the driving part can be fixed to a certain extent during sealing, thereby improving the sealing effect.

[0020] Preferably, the one-way valve includes two drive assemblies arranged opposite to each other, the two drive assemblies are respectively located on both sides of the moving valve core in the direction toward the first end and the second end, and the two drive assemblies are connected to the moving valve core through elastic members arranged opposite to each other.

[0021] In the present solution, the above-mentioned structure is adopted, and the two driving components are connected to the moving valve core through two elastic parts, so that the moving valve core and the driving components form a motion system as a whole. At the same time, the moving valve core can be driven to move from both sides respectively, so that the driving part outside the valve body can more easily drive the moving valve core to move to both ends, and the one-way valve core is easier to switch.

[0022] Preferably, the moving valve core is a ball, a ball groove is formed in the middle of the valve cavity, the first opening and the second opening are respectively opened at both ends of the ball groove, the ball is embedded in the ball groove and can move in the ball groove and close the first opening and the second opening, and the elastic member extends into the ball groove through the first opening and / or the second opening and connects to the ball.

[0023] In this solution, the above structure is adopted. By setting a ball groove in the middle of the valve cavity to accommodate the ball serving as the moving valve core, the ball can be limited to a certain extent and the travel distance required for the ball to switch the flow direction of the one-way valve can be reduced, making the overall structure simpler and more reliable.

[0024] Preferably, the valve body is further provided with detachably connected joint components at the first end and the second end of the valve cavity.

[0025] In this solution, the above structure is adopted to connect the pipelines through a detachable joint assembly, which can facilitate the disassembly of the one-way valve.

[0026] Preferably, the driving component is an electromagnetic coil arranged around the valve cavity, which can be energized to generate a magnetic field toward the first end or toward the second end and apply a corresponding electromagnetic force to the moving valve core to drive the moving valve core to move.

The direction of water flow through the valve core can be switched by switching the direction of the current, thereby simplifying the transmission structure.

[0028] The positive and progressive effect of the present invention is that the present invention discloses a one-way valve with adjustable one-way direction, and the driving component of the one-way valve can give forces in two different directions to the moving valve core so that the moving valve core can switch between two states. In the first state, the driving component applies a force toward the first end to the moving valve core, and the moving valve core moves toward the first end to the first port position under the action of the driving component and closes the first port. In this state, only when the water pressure direction is from the first end to the second end, the moving valve core will be pushed open and the water will flow from the first end to the second end and pass through the valve cavity. When the water pressure direction is from the second end to the first end, the moving valve core will be pressed tightly at the first port, so that it cannot be conducted. In the second state, the driving component applies a force toward the second end to the moving valve core, and the moving valve core moves toward the second end to the second port position under the action of the driving component and closes the second port. In this state, only when the water pressure direction is from the second end to the first end and the pressure applied by the water pressure on the moving valve core is greater than the driving force applied by the driving component, will the driving component be pushed open so that the water flows from the second end to the first end and passes through the valve cavity. When the water pressure direction is from the first end to the second end, the moving valve core will be pressed against the second port and thus cannot be conducted. This solution can realize the timely switching of the conducting direction of the one-way valve, can make the one-way valve more applicable to various scenarios, meet more usage requirements and reduce assembly and use costs.

[0053] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0054] Example 1

[0055] like Figure 1As shown, this embodiment discloses a one-way valve with adjustable one-way direction, which includes a valve body 1, a moving valve core 3 and a driving assembly. The valve body 1 includes a valve cavity for fluid to pass through, and the valve cavity includes a first end and a second end opposite to each other and a first port 101 and a second port 102 respectively arranged at the first end and the second end. The moving valve core 3 is located in the valve cavity, and the moving valve core 3 can move to the position of the first port 101 to close the first port 101 or move to the position of the second port 102 and close the second port 102. The driving assembly can apply a force toward the first end or the second end to the moving valve core 3 and drive the moving valve core 3 to move and keep the first port 101 or the second port 102 closed.

[0056] The driving component can give forces in two different directions to the moving valve core 3 so that the moving valve core 3 switches between two states. In the first state, the driving component applies a force toward the first end to the moving valve core 3, and the moving valve core 3 moves toward the first end to the position of the first opening 101 under the action of the driving component and closes the first opening 101. In this state, only when the water pressure direction is from the first end to the second end, the moving valve core 3 will be pushed open and the water will flow from the first end to the second end and pass through the valve cavity. When the water pressure direction is from the second end to the first end, the moving valve core 3 will be pressed against the first opening 101 and thus cannot be conducted. In the second state, the driving component applies a force toward the second end to the moving valve core 3, and the moving valve core 3 moves toward the second end to the second port 102 under the action of the driving component and closes the second port 102. In this state, only when the water pressure direction is from the second end to the first end and the pressure applied by the water pressure on the moving valve core 3 is greater than the driving force applied by the driving component, the driving component will be pushed open and the water will flow from the second end to the first end and pass through the valve cavity. When the water pressure direction is from the first end to the second end, the moving valve core 3 will be pressed against the second port 102 and thus cannot be conducted. This solution can realize the timely switching of the conducting direction of the one-way valve, can make the one-way valve more applicable to various scenarios, meet more usage requirements and reduce assembly and use costs.

[0057] like Figure 1 As shown, the drive assembly includes a drive part 2 and a transmission part 4. The transmission part 4 is arranged in the valve cavity and connected to the moving valve core 3. The drive part 2 can drive the transmission part 4 to move toward the first end or the second end and drive the moving valve core 3 to move.

[0058] The transmission part 4 is arranged in the valve cavity, which can improve the sealing performance of the one-way valve and avoid the situation where the transmission component is arranged outside the valve cavity, resulting in additional gaps and openings that reduce the sealing performance.

[0059] like Figure 1 , 2 As shown, the driving part 2 is arranged outside the valve body 1, and the driving part 2 drives the transmission part 4 to move through magnetic force.

[0060] The driving part 2 is arranged on the outside and drives the transmission part 4 located in the valve cavity by magnetic force without any physical connection. The moving valve core 3 inside the valve body 1 can be controlled from the outside of the valve body 1 without opening an additional opening or setting an additional connection transmission structure on the valve body 1, thereby improving the surface integrity of the valve body 1 and thus improving the sealing degree of the valve, and reducing the structural complexity to make the valve body 1 simple in structure.

[0061] like Figure 1 , 4 As shown, the driving part 2 includes a first magnetic part 21 , and the transmission part 4 includes a second magnetic part 41 . The first magnetic part 21 can move back and forth between the first end and the second end on the valve body 1 , and the second magnetic part 41 can move synchronously in response to the first magnetic part 21 .

[0062] The driving part 2 and the transmission part 4 respectively include a first magnetic part 21 and a second magnetic part 41 that can interact with each other. The movement of the first magnetic part 21 outside the valve body 1 drives the second magnetic part 41 to move synchronously in the valve cavity to realize the movement of the moving valve core 3 toward the first end or the second end. The structure is simple and the solution cost is low.

[0063] In this embodiment, the driving part 2 specifically includes a cylinder 22 surrounding the valve body 1 and a first magnetic component 21, forming a sleeve structure. The first magnetic component 21 is arranged between the cylinder 22 and the surface of the valve body 1. The movement of the cylinder 22 drives the first magnetic component 21 to move.

[0064] like Figure 1 , 4 As shown, the transmission part 4 includes an elastic member 42 , one end of the elastic member 42 is connected to the second magnetic member 41 , and the other end of the elastic member 42 is connected to the motion valve core 3 .

[0065] The transmission part 4 is connected to the moving valve core 3 through the elastic part 42, and can provide a certain holding force and restoring ability to the moving valve core 3 while transmitting kinetic energy, so that the water pressure needs to reach a certain level to overcome the force of the elastic part 42 to open the moving valve core 3, and the moving valve core 3 can be reset after the water pressure drops.

[0066] like Figure 3 , 4 As shown, the driving part 2 includes a fixing part, which is connected to the first magnetic part 21, and the fixing part includes a limiting groove 211. An elastic limiting part 11 is arranged on the valve body 1. The movable elastic limiting part 11 of the driving part 2 can be clamped in the limiting groove 211 to fix the driving part 2 at the first end or the second end position.

[0067] Through the cooperation between the elastic limiting member 11 and the limiting groove 211 , the driving part 2 can be fixed to a certain extent during sealing, thereby improving the sealing effect.

[0068] In this embodiment, the fixing part is formed on the side of the first magnetic part 21 facing the valve body 1, and the side is recessed inward to form a limiting groove 211. The surface of the valve body 1 has a plurality of elastic limiting members 11 arranged along the direction from the first end to the second end, and these elastic limiting members 11 can be embedded in the limiting groove 211 to fix the fixing part. At the same time, the elastic limiting member 11 has a certain deformation ability, and when the driving part 2 needs to move, it can be deformed appropriately and then disengaged or embedded in the limiting groove 211 without hindering the movement of the driving part 2.

[0069] In addition, if Figure 4 As shown, the inner side of the valve cavity and the second magnetic member 41 also have the same limiting structure, which will not be described in detail here. Through this limiting structure, the driving part 2 can be kept in the sealing position when the driving part 2 moves to the sealing position, and the moving valve core 3 will be opened and then turned on only when the water pressure reaches a certain level and the driving part 2 can overcome the elastic force of the elastic limiting member 11.

[0070] like Figure 1 As shown, the one-way valve includes two drive assemblies arranged opposite to each other. The two drive assemblies are respectively located on both sides of the moving valve core 3 in the direction toward the first end and the second end. The two drive assemblies are connected to the moving valve core 3 through elastic members 42 arranged opposite to each other.

[0071] The two driving components are connected to the moving valve core 3 through two elastic parts 42, so that the moving valve core 3 and the driving components form a motion system as a whole. At the same time, the moving valve core 3 can be driven to move from both sides respectively, so that the driving part 2 outside the valve body 1 can more easily drive the moving valve core 3 to move to both ends, and the one-way valve core is easier to switch.

[0072] like Figure 1 , 4 As shown, the moving valve core 3 is a ball, and a ball groove 10 is formed in the middle of the valve cavity. A first opening 101 and a second opening 102 are respectively opened at both ends of the ball groove 10. The ball is embedded in the ball groove 10 and can move in the ball groove 10 and close the first opening 101 and the second opening 102. The elastic member 42 extends into the ball groove 10 through the first opening 101 and / or the second opening 102 and connects to the ball.

[0073] By arranging a ball groove 10 in the middle of the valve cavity to accommodate the ball as the moving valve core 3, the ball can be limited to a certain extent and the travel distance required for the ball to switch the flow direction of the one-way valve can be reduced, making the overall structure simpler and more reliable.

[0074] like Figure 5As shown, the valve body 1 is also provided with a detachably connected joint assembly 5 at the first end and the second end of the valve cavity. The joint assembly 5 includes a joint body 50, a joint cap 53, a locking gasket, a joint claw 51, and a sealing ring 53. The joint body 50 is provided with a claw groove, a sealing groove, a silicone limit groove 211, and a wire outlet reserved port, and is the main part of the joint.

[0075] The pipeline is connected via the detachable joint assembly 5, which can facilitate the disassembly of the one-way valve.

[0076] Example 2

[0077] The structure of the one-way valve with adjustable one-way direction in this embodiment is substantially the same as that in the first embodiment, except that the driving component in this embodiment is an electromagnetic coil arranged around the valve cavity, which can be energized and generate a magnetic field in the direction of the first end or the direction of the second end and exert a corresponding electromagnetic force on the moving valve core 3 to drive the moving valve core 3 to move. By generating an electromagnetic force in an electromagnetic induction mode to drive the moving valve core 3 to move, the direction of water flow through the valve core can be switched by switching the direction of the current, thereby simplifying the transmission structure.
